For the purpose of illustrating my invention, I

have shown in Fig. 1 an ordinary egg case or crate which is indicated in its entirety at I9. This egg case comprises side walls II and I3 and ends walls I2 and I4, all of which may be conl0 structed of wood and which are nailed together in the usual manner. The end walls I2 and I e have attached to them cleats I 5 by means of which the case is stiilened. A bottom IE and a top II are attached to the end walls I 2 and I fl l5 and to the various cleats I5 and enclose the egg fillers and the eggs contained within the case.

My improved egg cushioning pad may be used solely as a cushioning pad both for the top and bottom of the case or the same may be used both 20 as a cushioningpad and as an egg flat, between the various llers in the case. In Figs. 1 to 5 the latter construction has been illustrated which will now be described in detail.

With the form of the invention shown in Fig. i, 25 a special type of filler is required, a number of such fillers being employed which are indicated These fillers consist of interlocking partitions I8 and I9 which.V are so arranged asfto form egg cells 2D in which the eggs 30 may be placed. The partitions I8 and I9 are constructed with projections I 2| and |22 which extend outwardly beyond the outer intersecting partition. In ordinary egg cases these projections abut against the end walls I2 and I4 of the 35 case. Between the various llers are placed egg iiats 26, 2'I and 28 which separate the layers of eggs and which protect the same and prevent breakage thereof through direct contact. At the lower portion of the case is provided a cushion 40 pad 29 and at the upper portion of the case is `provided another cushion pad 30. The Various egg flats are constructed of corrugatedmaterial as best shown in Fig. 3 and the various fillers 22, 23, 24 and 25 are notched as designated at 3| to fit into the corrugations of the egg flats.

All of the egg iiats 26, 21 and 28 and the cushion pad 29 are constructed in the same manner and only the cushion pad 29 'which is shown in 50 detail in Fig. 6 will be described. This cushion pad is constructed from a sheet of paper stock indicated at 32 which is of a width somewhat greater than the length of the case I9. Thissheet is corrugated to provide corrugations 33 55 which extend crosswise oivthe sheet and vlengthwiseof the case and which are of suitable depth to give the desiredcushioning effect to the-eggs resting thereon.V The corrugations 33 provide .valleys 49 in the upper surface ofthe sheet which alternate with adjoining ridges 4|. In the `construction ofV thecushioning pad, ribbons 34 f and 35 are gluedto the ridges 4| of thervarious corrugations 33 at the extreme ends thereof and function to retain the pitchof the corrugations throughout the extent thereof and to maintain n Ythe sheet in properV form. The ribbons 34 andY 35 are spaced from one another leaving the intermediate portions ofthe sheet with the corru- Vgations exposed on both sides thereof. Y rIn' the construction of the cushion pad the corrugated` sheetafter theribbons 34 and 35.

have been attached thereto is .crushed along two parallel lines 36 and'v3'l which form flanges 38'` and 39`at'lthe end of the sheet adapted torbe bent Y upwardly from the sheet as indicated in Fig. 3-

and 33.Y The ribbons 34 and 35 arel preferably andas disclosed in Fig. 2, and. tor further provide a body portion 46 intermediate vthe Vflanges 38 cogextensive with .the height of the flanges 3B.

Vand39 and extend abovey the lowermost surface ofthe corrugatedsheetwhen said flanges are c folded into operating position. The pitch of the vcorrugations 33 is such that certain of the valk leys 43 between the corrugations falls opposite the projections 22 of the partitions I8 'when the l iianges are foldedyoutwardly and'in which` said projections are received. When thel parts are assembled the` said projections are'full-y disposed.l

wit-hin said valleys and the ridges 4|' of the cor- Vrugations contact with the outer ofthe partitions |9. These corrugati'ons hence foirncushions for the ends of the llersandprevent injury to thek eggs through endwise movement of the lllers relative tothe case. Y

` As previously stated egg flats 26, 2-1 and 2,8V are identical with the cushion pad 29' andare dis,- posedV between'the various llers 22, 23, 24 and 25and between the. bottom filler 22 and the boteV tom i6 of the case.V At the upper portion of the Y case a plain cushion pad 4.2 is employed whichv is constructed from a corrugated sheet 43l having a flat back 45seeured to the same. This cushion pad is coextensive with 'the area of the case. and is not provided with flanges disposed alongy the ends of the case, the same as the' cushion pad 29. Such flanges are not vnecessary with this cushioning pad as the flanges-'of the egg flat 28 extend up along the ends of the upn Ypermost filler 25.

For the purpose of Vmore readily guiding the cushion pads 4into the case and especially when inverted as for the upper flat and' for guiding the fillers into position betweenY the corrugations ofthe iianges,v the following construction is employed. At-the end of each corrugation 33, on the flanges, the extreme endi of the ridges 4| thereof .are bent. back toward the ribbins 34 and 35 and tucked into the complemental valley on 'the opopsite sideof the sheet. clined edges 6l on the corrugations which con-.

verge toward` thel said ribbons. Such edges Y serve to: guidethe filagesinto position when the Yupper cushion pad is inserted into thel case and "also serve to guide Vthe iillers into position ber, tween Vthe anges.

.The Yuse .of lthe invention is as follows. 'Ihe cushion pads and egglatsareconstructed planiforin, the twor flanges 38 and 3.9.,1ylng inthe plane of the body portion 46 of the egg flat. The

This forms in-V stock?, however,A is crushed along the lines 36 and 3'| as previously explained at the locality of the inner edges of the two ribbons 34 and 35"and the inclinededge 6| previously formed. When desired for use the two flanges 38Yand 39 are bent 5 upwardly along theV lines 36 and 31. In Fig. 3 flange 351` has been illustrated as partly bent. When the vtwo'iianges are at right angles'vtothc Vrbody portion, the ii'ats and cushion pads may be K .inserted inthe case. The cushion pad 29 is first -10 rplaced upon the bottom of the Vcase. with 'anges.

38 andl 39 thereof engaging the end walls i2 and I4 of thecase. Y The egg case filler 22'V is next applied',the. partitions i9 thereof'beingarranged Y v to. extend. crosswise of the corrugations and so 15 raised portions orfridges 49 of the corrugations 33, beingspaced from the bottom of the casefandf being thereby cushioned and protected from inv jury. After the various egg cell-s 20 have been;

illedwith eggs,` the egg' hat 2-6 isY next. placed upon the ller 22 with its iianges 38 and 39 Ven-` 305,5

gaging the end `wal1s|2 and I4 of the case; Fil-ler 23 is next' applied inexactly therf-same man-neras iiller 22.and thefegg (cells. or'com-` pertinents yZilfftherein filled witheggs.. The rei-V 1 maining egg flats and fillers are then succes- 35` sivelyinstalled in the case. and when the case is completed-cushion pad 43 is applied and the. cover l? secured tothe Acase through'cleats I5 thereof. It wil-l be noted that:A with this construe tion a cushion member is provided at the ends of; al 'E each layer ,of eggs which serves to preventinjury to the eggsv through end-wise movement thereof.. At the same time a cushion is provided between. each layer of eggs and between the lowermos layer and the bottom of the case. l 55 If desired, my invention'may be used `solely as a cushion pad as illustrated in Fig; 6. In such case two cushion pads 5| and 52 are employed kwhich are .placed in the topv and bottom of the case.V The cushion pad 5| isv applied in exactlygao' the same manner asthe cushion pad 29 andis constructed identically the same as this cushion pad. With this form vof the invention, standard egg case iillers such as indicated at 53 are ern-f.

ployed which are constructed oi the usual heights. f

and without the notches in either of the partition walls. These egg case iillers rest directly upon the ridges 42| ofV the eorrugati'ons33,iof the cushion pad instead of tting down into the same.

The ends 54 of the partitions of these `llersreov however, extend into the valleys 40 ofthe corruf .gations of the Vflanges 38 and 39, the same as in the other.r form of' thel invention.` After the egg cells within the fil-ler 43 have been filled with eggs,

a plani'form sheet of material 55 or anegg flat 55.

of any'othertype is laid upon the llers 53V.VV Thereafter'succeeding fillers 56. and. other egg flats 51ers successively placed upon` one another until the entirecase is lled. Theplast. cushion pad'52 isthenapplied'which is accomplishedo by inverting .the same and. by inserting the anges 38' and 1 39 n thereof downwardly along .the 'endg Lwalls vl2 and |4of the casewith theends .'54V oi."v

the `uppermost iillperg594 received within'-v the'valf leys thereof, Inclined edges'll assist ingilidig'y'g'- the cushion pad in place. By means of this construction the case is cushioned at the top and bottom to prevent injury to the eggs and a certain amount of endwise cushioning is also procured which further assists in protecting the eggs within the case.

My invention is highly advantageous in that the eggs contained within the ordinary egg case are more fully protected and cushioned than with other types oi cushion pads. The cushion pad can be used either as a cushion pad or as an egg iiat so that but a single type of construction is needed for either use. With my improved invention cushioning in an endwise direction is procured which is particularly advantageous where eggs are shipped in railway cars. The egg fillers are easily applied to the flats or cushioning pads and are firmly held in position thereby. The cushion pads can be constructed from a relatively small amount of material and from a fairly inexpensive paper stock.

Changes in the speciiic form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
